The DLC bundles all of the previous content drops along with the latest multiplayer map Black Box and two Spec Ops missions; Black Ice and Negotiator.
Content Collection #1 will be available March 20 for non-Elite Xbox 360 players, PlayStation 3 and PC players will have to wait until a later date.
EGM’s TAKE: Whether Modern Warfare 3 players will still be interested in this DLC considering how long they’ve had to wait is yet to be seen. But more than likely they will eat it up as usual and just further justify Activision’s actions. If you keep on buying and downloading they will continue to see how far they can push you.
